Actions you need to perform to create class extension are: 1. use [ExtensionOf(classStr(<class>))] 2. mark the class as "final" 3. extension class name has to end with "_Extension" 4. any extended method has to have "next"

Selected Answer: A
A. Mark the class as final: To create an extension class, the class must be marked as final to comply with the extensibility framework. This prevents the extension class from being inherited, as it is instantiated by the runtime system. Additionally, the class must be public and use the [ExtensionOf] attribute, but among the provided options, marking the class as final is a required action explicitly stated in the documentation. https://learn.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/extensibility/class-extensions
